Abstract: A multi-lens camera module making use of a single image sensor comprising first and second lens modules, an image acquisition module, a refracting module, and a shielding module. The refracting module refracts light from either the first lens module and/or the second lens module, the shielding module allowing light to enter only one of the first or second lens modules by masking the other. The first and second lens modules can share one image acquisition module, which saves cost and interior space of the camera module and thus of the electronic device using such camera module. An electronic device comprising the camera module is also provided.

Abstract: A dual-lens camera system includes a first lens, a second lens, an image sensor corresponding to a position of the first lens, and a reflecting assembly. The reflecting assembly includes a first reflecting member and a second reflecting member corresponding to a position of the second lens. The first reflecting member is movable between a first position at which an optical path from the first lens to the image sensor is blocked but an optical path from the second reflecting member to the image sensor is not blocked, and a second position at which the optical path from the first lens to the image sensor is not blocked but the optical path from the second reflective member to the image sensor is blocked. Only one image sensor is used in the dual-lens camera system, which saves cost and takes up less internal space of the electronic device.

Abstract: A grating measuring module includes a light source, a collimating device, a first grating, a second grating, and an image sensing chip. The first grating is arranged on an optical path of the collimating device and the second grating is arranged on an optical path of the first grating. Each of the two gratings comprises a first pattern and a plurality of second patterns locating at the both sides of the first pattern. The first and second gratings can each be attached to an object which may be displaced in relation to another object, so allowing light of a certain pattern to pass depending on the magnitude of the displacement. The image sensing chip arranged on an optical path from the second grating receives light emitted from the light source and forms an image from which a displacement can be calculated and displayed.
